A radiation pyrometer has hot and cold junctions 10 and 20 of a thermopile mounted to lie on opposite sides of a block 6, an inner casing 8 surrounding the thermopile except for an aperture 11 near the hot junctions, a tube 12 with an internal reflecting surface connecting with the aperture 11, and an outer casing 15 providing a jacket for the flow of cooling fluid around the inner casing 8. The thermopile comprises blades 3 and 4 of " Constantan " and " Manganin " (Registered Trade Mark), only one pair of which can be seen in Fig. 1, soldered together at their ends to form rows of hot and cold junctions, the row of hot junctions lying in the aperture 11 of the inner casing 8 about which aperture is secured one end of the tube 12 which may be conical and the internal reflecting surface of which may be gold-coated. The outer casing 15 may extend along the tube 12 leaving an annular orifice for the exhaust of air introduced at an inlet 17. Alternatively the outer casing 15 may be sealed off to surround only the lower portion of tube 12 and an outlet port may be provided in which event water may be used as the cooling fluid. The tube 12, instead of being joined end on, may be joined transversely with the aperture 11 in register with a slot in its side wall, with the object of measuring the radiation of a current-carrying conductor passing axially through the tube. The space in the inner casing 8 may be separated from the space in the tube 12 by means of a silver or aluminium disc blackened on the side facing the tube and making contact with the hot junctions of the thermopile on its other side. The disc may be heated by passing a current through it in order to calibrate the thermopile. Alternative to the use of a disc a screen of metal lamellµ, through which current may be passed in series or in parallel, may be used.

Abstract: 1,240,023. Windscreen wipers. REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGOT. 16 July, 1969 [7 Aug., 1968], No. 35932/69. Heading A4F. [Also in Division H2] When switch 3 engages contact m, a motor M is continuously energized to drive a windscreen wiper. When the contact a is engaged, the motor keeps rotating until a cam 1 closes contacts 2c whereby the armature is short-circuited provided that contacts 5a are closed. Closure of a rheostat switch 4 energizes a heating-wire 6 through contact arm 7, expansion of the wire causing spring 8 to move the arm 7 from contact 5a to contact 5b after a period of delay. The motor is re-started so that the cam 1 closes contacts 2a and the motor continues to be energized in series with solenoid 9. Arm 7 is then attracted to re-close the contacts 5a and prepare for the next cycle of operations. In another arrangement, the wire 6 is insulated from arm 7 and is connected directly to the arm of switch 2. The solenoid 9 is replaced by a snap-action spring associated with the arm 7. The cooling of the wire 6 is retarded by connecting an additional resistor between the junction of elements 6, 11, and earth, Fig. 2 (not shown).

Title: Activation of ferroelectric materials
IPC: H01G7/02
Filed: 1957-11-19
Abstract: 855,567. Piezo-electric elements. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION]. Nov. 19, 1957 [Dec. 7, 1956], No. 36029/57. Class 40(8). A ferro-electric body is polarized to impart desirable electrostrictive properties by producing varying internal strains in the body whilst maintaining in it a unidirectional electric field of activating magnitude. A D.C. activating voltage of about 1475 volts per mm. may be applied to the electrodes of an oil-immersed element either at room temperature or at 85-90‹ C. The voltage is applied in pulses of three seconds duration spaced two seconds apart and is allowed to fall to a low value or to zero between pulses. Each pulse shocks the element into vibration at its natural frequency. In an alternative method a D.C. activating voltage from a source 14, Fig. 6, and an A.C. voltage from a source 20 are applied simultaneously to an oil-immersed element 10. The two sources are isolated from each other by elements 21, 22, 25. The frequency of the A.C. voltage is preferably equal to the resonant frequency of the element. The capacitative reactance of the element is tuned out by means of a variable inductance 26. The oil in the oil bath 15 may be maintained at room temperature and the element heated to a desired activating temperature (e.g. 85-90‹ C.) by suitably adjusting the amplitude of the A.C. voltage. Since the resistance of the element varies with temperature, readings of the ammeter 23 in the D.C. circuit will give an indication of its temperature provided the voltage of the source 14 is maintained constant. The element is cooled by the oil bath when the A.C. voltage is switched off, the D.C. voltage being maintained during cooling. The invention may be applied to all ferroelectric materials, numerous examples being given in the Specification. The element may be in the form of an annulus with electrodes on its side surfaces. Alternatively, two series of electrodes 11a, 12a, Fig. 4, connected as shown, may be provided. Each electrode embraces the annular element.

Abstract: 828,549. Measurement of low pressures. MULLARD Ltd. Sept. 11, 1957 [Nov. 28, 1956], No. 36384/56. Class 40 (1). Apparatus for measuring low gas pressure comprising means (such as a heater S) for imparting kinetic energy to molecules within the gas and a resilient metallic member v disposed within the gas and adapted to be displaced by molecular bombardment has provision for the periodic interruption of the bombardment. As shown, the heating member s is surrounded by a rotary cage o with alternate quartz shutters p and gaps q. The apparatus is supported by means of bellows u to limit vibration from the driving motor. As the quartz is transparent to infra-red radiation the radiation pressure due to s provides a constant mechanical bias on the member v. The periodic change in the capacitance between member v and a fixed member r operates an indicator in known manner. In another embodiment described with reference to the Provisional Figure (not shown) the molecular bombardment is interrupted by an oscillating quartz shutter mounted on a leaf spring and the electrical signal is derived as a potential across the resilient member due to its motion in a fixed magnetic field.

Title: Process for stabilizing textile materials against dimensional changes and producing durable mechanical effects
IPC: D06M13/137
Filed: 1954-12-16
Abstract: A process for the dimensional control of cellulosic or cellulose-containing textile materials comprises treating the material with an aqueous solution of an acetal which has a boiling-point above 125 DEG  C. and is derived from an aldehyde containing up to 8 carbon atoms and an alcohol preferably containing 1-4 carbon atoms, followed by heating the treated material in the presence of an acidic or potentially acidic catalyst at a curing temperature of at least 121 DEG  C., generally for from 0.5 to about 10 minutes.  Many examples of acetals, which may be hydroxy- or alkoxy-substituted or cyclic, are given, but those preferred are di-(2-methoxyethoxyethyl) formal, malonaldehyde tetramethyl acetal, glyoxal tetra-(2-methoxyethyl) acetal, malonaldehyde tetra-(2-methoxyethyl) acetal, and glyoxal tetrabutyl acetal.  The concentration of acetal in the treating bath is generally 0.5-25 per cent.  Catalysts mentioned, which may be incorporated in the treating bath in amounts of from 5-200 per cent by weight of acetal present, are aluminium chloride, stannic chloride, aluminium-sulphate, zinc chloride, sodium bisulphate, sodium or potassium alum, ammonium chloride, oxalic acid, or dimethyl oxalate.  The material, after treatment in the bath, may be dried to a moisture content of about 11 per cent by weight of the dry textile, and the surface may be mechanically worked either before or during the curing treatment. The cured fabric may then be washed lightly with a detergent and a mild alkali, rinsed thoroughly, and dried in a relaxed state.

Abstract: 1,063,973. Bread slicing machines. BATTLE CREEK PACKAGING MACHINES Inc. Aug. 27, 1965, No. 36858/65. Heading A4C. [Also in Division B8] A bread slicing machine comprises a plurality of parallel, inclined band saws 18 to and through which loaves are continuously fed by a system comprising three, series arranged endless conveyers 3, 6 and 7 driven from a common drive shaft 20 such that the feed conveyer 7 travels faster than the intermediate conveyer 6 and the latter in turn travels faster than the supply conveyer 3 whereby the loaves are carried at progressively increasing speed in their advance to the saws 18. The intermediate and feed conveyers 6, 7 carry tiltably mounted flights 132, 144 respectively which are spaced apart to accommodate a single loaf therebetween and are guided by plates 133, 138 to pivot outwardly to their loaf engaging positions on the top runs of the conveyers. A cam operated double gate 92, 93 is located between the supply conveyer 3 and the intermediate conveyer 6 to pivot in timed relationship with the conveyer system between a blocking position, which prevents transfer of a loaf to the intermediate conveyer 6 until there is an empty pocket ahead of a flight bar 132, and a lowered. position permitting the transfer. The gates 92, 93 are timed to move to a blocking position prior to the complete transfer of a loaf so that they assist the transfer by elevating the trailing part of the loaf. The supply conveyer 3 comprises transverse wire grids or links 83 presenting a smooth surface which facilitates their smooth sliding beneath a blocked loaf. In operation each loaf is pushed halfway through the saws 18 by a pusher flight 144 and then completely through by a following loaf. Retarding fingers 236 at the sides of the intermediate conveyer 6 serve to brake a loaf to ensure that it is fully backed against an advancing flight bar 132. A solenoid switch 155 senses the presence of a loaf adjacent the gate 92, 93 to prevent opening of the latter until a point in the cycle at which the loaf falls accurately ahead of a flight bar 132. The machine includes means for accurately centering a loaf and includes means (Fig. 4, not shown) for guiding each bandsaw 18 in such manner that the slice width may be selectively adjusted.
